Please apply some kind of privacy control to external services

I think some attention could be paid to the way locations are shared outside of Brightkite. I really like the privacy levels you allow us to set for Brightkite users, but my entire home address gets sent to Twitter since I have that sharing feature turned on. I don't really want that to happen.

I'd rather stick with only allowing my trusted Brightkite friends to see my home address, and perhaps something like a location alias being sent to Twitter and other external services. So when I SMS that I'm @home, my Brightkite friends can see my full address, but maybe the Twitter message is simply "David's @home."
